When the injection angle control lever 9 is moved in the left and right directions, the DC motor 48 of the second angle conversion device 43 moves to the right or the left as shown in FIG. Is rotated. Therefore, the chain saw prog 47 provided at the front end is rotated, and the power is transmitted to the chain 46 to rotate the rotary plate 44 at the lower end of the chemical injection device F.

At this time, since only the bellows tube 4l coupled to the upper side of the rotating plate 44 is rotated, the position of the drug injection device (F) is variable.

That is, the combination of the lower end of the rotating plate 44 and the compressed air outlet 40 above the blower E is coupled to enable the sleeve, and the casing and turbofan casing 27 of the second angle conversion device 43. ) Is a structure coupled to each other by a predetermined coupling means (not shown).

Therefore, when the injection angle control lever 9 of the remote controller 5 is moved to the left or right direction, the bellows type tube 41 of the drug injection device F is rotated 360 °, and the user can apply the drug injection as described above. After the device F is moved to a predetermined position, the angle of the bellows tube 41 can be adjusted by moving the injection angle control lever 9 of the remote controller 5 up and down. When the lever 9 is moved upwards and downwards, as shown in FIG. 3B of FIG. 3B, the DC motor 49 in the apparatus 42 of FIG. 50) rotate.

Meanwhile, as the chain sprocket 50 is rotated, the rotating plate 52 is rotated, and the link 51 integrally coupled to the rear surface thereof is axially rotated to bend the bellows tube 41.

Accordingly, the bellows-type dive 41 of the drug injection device F, which is sprayed with pesticides by the operations of the first and second angle conversion devices 42 and 43, is angle-shifted to effectively spray pesticides to a desired position of the user. You can do it. In other words, it is possible to maximize the pesticide spraying efficiency by simply adjusting the drug spraying device (F) using the remote controller 5 without changing the overall position of the pesticide control machine.

In addition, the one side wall of the metal barrel 54 of the chemical injection device (F) that is spraying the pesticide is equipped with an illumination light 73 has the advantage that can be effectively spraying pesticides, especially at night, preferably metal barrel ( Half of the plurality of chemical injection nozzles 57 mounted at the tip of 54) has a shutoff valve on its own to adjust the spraying amount of the pesticide, and to control the output of the engine connected to the blower (E). It is desirable to provide a means for increasing (not shown) to expand the effective spray radius of the pesticide by linking with the engine layer force button 8 of the present invention.

As described above, the pesticide control device according to the present invention maximizes the effective spraying distance of the pesticides by using the turbo pen method of the blowing device (E) in which the feeding pressure of the pesticides is generated, and also the drug spraying ground (F) where the spraying of the pesticides is performed. It is very fun to use by allowing the position and angle to be changed remotely, and the pesticide spraying can be done only at the desired position, which doubles the spreading efficiency and the pesticide spraying is done only where it is needed. It is a very useful invention that is prevented.
